Powel House Museumhttp://www.philalandmarks.org
Step into one of America's grand Georgian homes and enter the world of the colonial elite. Samuel Powel, Philadelphia's Patriot Mayor, and his wife Elizabeth Willing were preeminent hosts, who frequently entertained the famous names of the Revolution. Visit the ballroom where George Washington danced, ponder John Adams "sinful feast," and stroll through the tranquil colonial garden.
